Benefits of technology

This patent is about a new type of plastic that can be used to make containers and pipes for organic solvents. This plastic has the added benefit of being antistatic, which means it can resist the accumulation of static electricity. This is important because organic solvents can damage or impair the antistatic properties of some plastics. The invention provides a solution by creating a long-lasting and effective antistatic plastic that can maintain its antistatic properties even when in contact with organic solvents for a long period of time. Additionally, the invention includes a method for making an antistatic polyolefin fiber that is effective in resisting water and other liquids. Overall, this invention allows for the creation of more durable and reliable materials for the storage and transportation of organic solvents.

Problems solved by technology

Such electrification presents a risk of ignition or explosion of an organic solvent or flammable gas that is stored in the containers or passed through the pipes.
However, since polyolefin resins have electrical insulation properties, and there is a problem of being easily electrically charged by friction and the like and thereby attracting dust and dirt in the surroundings.
Particularly, in workwears and the like using such nonwoven fabrics, attraction of dust and the like is problematic.
Further, nonwoven fabrics are used in transport materials and packaging materials of electric / electronic components and instruments, and the generation of static electricity presents a major problem since it causes malfunction and attracts fine dust and the like.

[0301]To a separable flask, 656 g of 1,4-cyclohexane dimethanol, 708 g (4.85 mol) of adipic acid, 0.7 g (0.01 mol) of phthalic anhydride and 0.7 g of an antioxidant (tetrakis[3-(3,5-di-tert-butyl-4-hydroxyphenyl)propionyloxymethyl]methane: ADK STAB AO-60, manufactured by ADEKA Corporation) were added, and these materials were allowed to polymerize for 5 hours under normal pressure with the temperature being slowly increased from 160° C. to 210° C., and then for 3 hours at 210° C. under educed pressure, whereby a polyester (A)-1 was obtained. This polyester (A)-1 had an acid value of 28 and a number-average molecular weight (Mn) of 5,400 in terms of polystyrene.

[0302]Next, 600 g of the thus obtained polyester (A)-1, 300 g of polyethylene glycol having a number-average molecular weight of 4,000 as a compound (B)-1 having hydroxyl groups at both ends, 0.5 g of an antioxidant (ADK STAB AO-60) and 0.8 g of zirconium octylate were added and allowed to polymerize at 210° C. for 7 hours und...
